Abstract
The present invention relates to a new 3D TV receiver that can receive and decode a 3D TV broadcast signal that compresses and encodes left and right moving image data received from two left and right cameras in order to express a three-dimensional effect of a screen.
The biggest difference between existing digital TV broadcasting and 3D TV broadcasting is classified according to whether the three-dimensional effect of the screen can be expressed. In order to express a three-dimensional effect, two left and right cameras corresponding to the left and right eyes are required, and since data is input through the two left and right cameras, the data to be processed is doubled compared to the existing digital TV broadcasting data, and the processing capability of the broadcasting system is increased. About twice as much.
In particular, in the case of using a more complicated H.264 coding method [Document 2] in addition to the MPEG-2 coding method [Document 1] used in existing digital TV broadcasting, the processing power is required to be more than doubled.
Similarly, the 3D TV receiver requires at least twice as much data processing capacity as conventional digital TV reception, and this requires a high performance dedicated decoding processor that is more powerful than the decoding processing processor used for digital TV reception. However, since there is no dedicated decoding processor that can decode 3D TV broadcast data, and it is difficult to implement it in a short period of time, it may be a problem to spread 3D TV broadcast service early.
In order to solve the above problems, instead of using a 3D TV dedicated decoding processor, the present invention allows a 3D TV broadcast signal to be received early by decoding the 3D TV encoded data using a general computer that already has a high performance processor. It is to provide a new device and method that can be done.
To this end, the 3D TV receiver of the present invention includes a digital TV receiver, a USB connector, and a general computer.
The present invention is very useful in the early 3D TV receiver market because it is possible to easily configure the 3D TV receiver using a general computer without using a 3D TV dedicated decoding processor to receive and process the 3D TV broadcast signal. Can be used.
Description
The present invention relates to a new 3D TV receiver capable of receiving and decoding 3D TV broadcast signals that compress and encode left and right moving image data input from two left and right cameras in order to express a three-dimensional effect of an object.
[Document 1] ISO / IEC 13818-2: 2000, "Information technology, Generic coding of moving pictures and associated audio information: Video"
ITU-T Recommendation H.264 (2003), "Advanced Video Coding for generic audiovisual services" | ISO / IEC 14496-10: 2003, "Information technology, Generic coding of audio-visual objects-part 10: Advanced video coding"
Unlike conventional digital TV broadcasting, 3D TV broadcasting requires two left and right cameras corresponding to left and right eyes in order to express a three-dimensional effect, and data to be processed compared to existing digital TV broadcasting data because data is input through two left and right cameras. Is doubled, and the processing power of the broadcasting system is about doubled.
In particular, in the case of using a more complicated H.264 coding method [Document 2] in addition to the MPEG-2 coding method [Document 1] used in existing digital TV broadcasting, the processing power is required to be more than doubled.
Similarly, the 3D TV receiver requires at least twice as much data processing capacity as conventional digital TV reception, and this requires a high performance dedicated decoding processor that is more powerful than the decoding processing processor used for digital TV reception. However, since there is no dedicated decoding processor that can decode 3D TV broadcast data, and it is difficult to implement it in a short period of time, it may be a problem to spread 3D TV broadcast service early.
In order to solve the above problems, instead of using a 3D TV dedicated decoding processor, the present invention allows a 3D TV broadcast signal to be received early by decoding the 3D TV encoded data using a general computer that already has a high performance processor. We want to provide a new device that can do that.
To this end, the 3D TV receiver of the present invention includes a digital TV receiver, a USB connector, and a general computer, and the 3D TV broadcast data received through the digital TV receiver and the USB connector is decoded using a computer built-in processor. . In fact, a processor embedded in a computer is generally capable of parallel processing at a high speed, and thus far more powerful than a dedicated processor used for a specific purpose, so that it is relatively easy to perform real-time decoding of 3D TV broadcast data.
Therefore, the 3D TV receiving apparatus of the present invention decodes a digital TV receiver for receiving a 3D TV broadcast signal, a USB connection for transmitting the received 3D TV broadcast data to a computer via USB, and 3D TV broadcast data received through the USB. And the computer to restore the original left and right video data.
The present invention makes it possible to easily configure a 3D TV receiver using a general computer without using a 3D TV dedicated processor to receive and process a 3D TV broadcast signal. It can be usefully used.
Hereinafter, with reference to the accompanying drawings will be described in detail the operating principle of the preferred embodiment of the present invention.
1 is a block diagram of a 3D TV receiving apparatus according to the present invention.
The 3D TV receiver of the present invention includes a digital TV receiver 11 for receiving a 3D TV broadcast signal, a USB connector 12 for transmitting the received 3D TV broadcast data to a computer via USB, and a 3D TV received via USB. And a computer 13 for decoding broadcast data to restore original left and right moving picture data.
The digital TV receiver 11 receives the 3D TV broadcast signal, converts it into a digital data form, and transfers the same to the USB connection unit 12. The digital TV receiver 11 is implemented using a commercial digital TV receiver module as it is used to receive an existing digital TV. The 3D TV broadcast signal is created by adding information (for example, right camera input information) that can express a three-dimensional effect while maintaining the existing digital TV broadcast signal form. That is, the form of the 3D TV broadcast signal is the same as the reference digital TV signal, and only the information content is different. Therefore, it is possible to receive a 3D TV broadcast signal using the existing digital TV receiving module as it is.
The USB connection unit 12 converts the 3D TV broadcasting data received from the digital TV receiving unit 11 into a USB transmission format, and transmits it to a computer via USB. The USB connection unit 12 is implemented using a commercially available USB chip, and serves to transfer the contents of the 3D TV broadcast data received from the digital TV receiver 11 to a computer without any processing by using a known USB communication method. .
In addition, the digital TV receiver 11 and the USB connector 12 are located in the same board or stacked board form because signals to be transmitted must be closely connected.
The computer 13 decodes the 3D TV broadcast data received through the USB to restore the original left and right moving picture data input from the two left and right cameras. As a decoding method used for restoring the left and right moving image data, the MPEG-2 method [Document 1], the H.264 method [Document 2], and the like used in digital TV broadcasting are used. In addition to the video data, the computer 13 can also restore the audio data. The decoding processing of the 3D TV broadcast data is implemented entirely in software using a processor built in the computer 13. The reconstructed left and right moving image data is output to a 3D display device to express a three-dimensional effect, and the reconstructed audio data is output to a speaker to output sound.
In addition, when the digital TV receiver 11 receives the 3D TV broadcast signal, it is necessary to select a specific channel among several channels. The channel selection information necessary for this is transmitted from the computer 13 through the USB transmitter 12 to the digital TV receiver ( 11).
